This page presents the data development documentation for Battery Electrochemistry for all sites
The data ingestion phase for batteries follows the standard approach describe on LB Data Dev Architecture - General.

|---|---|---|---|
ELN EWHA BOLLATE | ELN current template | This is a standard ELN spreadsheet for all sites | |
ELN BOLLATE | ELN historic template | This is a ancient format for ELN spreadsheet for BOLLATE. The data is still necessary but new spreadsheet won't be created. | |
ELN Battery mapping | ELN historic template | This is a ancient format for ELN spreadsheet for EWHA. The data is still necessary but new spreadsheet won't be created. | |
| ELN MuSigma | pré-ELN | This spreadsheet has EWHA data before starting using ELN. There is no new data being added to it. All data is already ingested. | |
| ELN Separator data Mapping | ? | Existing spreadsheet to be loaded to BQ |
*Data Status: HOT: Data currently being updated at the source. It should be loaded regularly. COLD: No data changes at the source. It should be loaded just once.
The list of the spreadsheets/tables extracted from JSON files coming from ELN can be found in the Data Mapping of the next section.

The instrument files are, most of them, manually added to a Google Driver's folder or a folder in lab servers.
The spreadsheet Where to find instrument files? has the full list of instrument folders and location:

No data mapping needed as the data is copied exactly as the source.
The data preparation phase for batteries follows the standard approach describe on LB Data Dev Architecture - General.
Local CSV/XML/TXT file → <Load> → Cloud Storage/Staging BigQuery |
The spreadsheet below presents all data transformation between the raw files (extracted files) and a BigQuery delta table. Some files are unstructured and semi-structured. This steps aims to structure the files in the target table format and checking if the column's type (schema) are conformed expected.

The data integration phase for batteries follows the standard approach describe on LB Data Dev Architecture - General.
Staging BigQuery → <Transform> → ODS BigQuery |
The spreadsheet below presents all data transformations between the tables on Staging and ODS. This steps aims to add some calculations and intelligence to the data. Not all tables will need passing through this step.
This spreadsheet shows how to align all cyclers in just one commun table schema:
The job...
The data presentation phase for batteries follows the standard approach describe on LB Data Dev Architecture - General.
ODS BigQuery → <Transform> → DW BigQuery → <Expose> → DM BigQuery |
In order to load DW the following jobs/scripts are used:
For the DM dataset(s), no need of jobs as there are no steps to load it. All data is presented as views.
The data model presents the tables/views presented on DW/DM dataset and the relation between them.
{Add model}
All the jobs are run in sequence under the follow job and project name on TAC/Talend Cloud:
| Project | Job/Flow |
|---|---|
| RnI_ACN_Battery | F000_RnI_ACN_Battery_Orch_Flow |
| RnI_Battery_ELN | |
| RnI_Battery | |
| RnI_Battery_BOLLATE |
